After death, huge ape gets internal examination (9)

I believe the answer is:

endoscopy

I'm a little stuck... Click here to teach me more about this clue!

'internal examination' is the definition.
'endoscopy' can be an answer for 'examination' (I have seen 'Patient examination' mean 'endoscopy' so perhaps 'examination' could also mean 'endoscopy'). I'm not certain of the 'internal' bit.

'after death huge ape' is the wordplay.
'after' says to put letters next to each other.
'death' becomes 'end' (synonyms).
'huge' becomes 'os' (abbreviation for outsize).
'ape' becomes 'copy' (synonyms).
'end' next to 'os' is 'endos'.
'endos'+'copy'='ENDOSCOPY'

'gets' acts as a link.

Can you help me to learn more?

(Another definition for endoscopy that I've seen is " Patient examination".)

I've seen this clue in The Independent.
